Press to make corrugated metal siding

thingiverse

I'm working on a coal mine for my HO scale railroad, thinking of making it look like corrugated metal siding. To lay out the walls as I need, I've decided to print them face down so no texturing of the outer walls will be possible. I tried a press pattern set to form aluminum foil into corrugated sheet metal and was surprised by the results. The patterns in HO scale resulted in corrugations just under 3.5 inches - a bit oversized for the scale, but they look pretty good. I've uploaded 0.7mm and 0.5mm patterns as well, but with my 0.4mm nozzle, I might be getting close to my limit. If I can get it to slice and print well, I'll upload pictures of the resulting aluminum foil imprints. I also added a large version of the 1mm pattern if you want sheets for O Scale. I printed in ABS using Cura 3.6 with 0.2mm resolution but used the experimental feature adaptive layers to use a finer resolution in the corrugations (max variation 0.15mm, variation step size 0.05mm, threshold 20). With an FDM printer, I'd love to see if someone can print the small pattern (I'm sure to try!). Other settings include: 15% infill, top layers 3, bottom layers 2, sides 3. I printed two and sandwiched cut pieces of heavy-duty aluminum foil between them. I plan on gluing them one by one to the walls of the mine.
